AJR Podcasts

As healthcare moves into a new era of increasing information vulnerability, radiologists should understand that they may be using systems exposed to altered data or data that contains malicious elements. This podcast explains the vulnerabilities of DICOM images and discusses requirements to properly secure these images from cyberattacks. For more on this topic, read Benoit Desjardins' article from...

Erin F. Alaia provides an overview of stener-like lesions of the superficial medial collateral ligament of the knee and MRI features associated with this injury pattern. You can read more in December's issue of AJR . https://www.ajronline.org/doi/full/10.2214/AJR.19.21535

Donna Blankenbaker, Miriam Bredella, and Tetyana Gorbachova discuss the nomenclature of nonneoplastic conditions affecting subchondral bone through a review of the medical literature and expert opinion of the Society of Skeletal Radiology Subchondral Bone Nomenclature Committee.

Julia Crim discusses the correlation of radiography findings with findings of gross and microscopic histopathologic analysis to assess the usefulness of radiography in preoperative assessment for hip arthroplasty.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.19.21277

Naveen Subhas discusses the current role of dual-energy CT in musculoskeletal imaging primarily focusing on nongout entities, including evaluation of bone marrow edema, bone tumors, as well as reducing metal artifact.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.19.21095

Brian Chan discusses how image-guided injections targeted to the symptomatic ossicle can confirm suspected diagnoses and predict therapeutic outcomes before surgical intervention.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.18.20761

Increasing reliance on MRI for the evaluation of sacroiliitis requires that radiologists be familiar with the normal appearance of the developing sacroiliac joint. In this episode, Nancy Chauvin describes age-related MRI features of the sacroiliac joints in healthy children.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.18.20708

A discussion about the least arthritic or technically most straightforward joint injection when a fluoroscopically guided therapeutic injection is ordered for the second and third tarsometarsal joint, the naviculocuneiform joint, or both. For more on this, read Barry G. Hansford's article in AJR . https://www.ajronline.org/doi/full/10.2214/AJR.18.20347

How to determine the most accurate imaging techniques to measure glenoid bone loss in anterior glenohumeral instability through a systematic review of existing literature. For more on this, read Soterios Gyftopoulos's article in AJR . https://www.ajronline.org/doi/full/10.2214/AJR.18.20504

Tony Wong discusses his study on how to determine whether ulnar collateral ligament insertion below the articular margin exists in the pediatric population and whether MRI features can be used to identify insertional UCL injuries in overhead athletes that are symptomatic or require surgery.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.18.20474

Matthew Bucknor discusses his study in  AJR  that identifies clinical factors and radiographic characteristics associated with positive culture results from bone biopsy in cases of suspected osteomyelitis.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.18.20125

Contrast material often extends from the radiocarpal joint into the proximal soft tissues adjacent to the ulnar aspect of the ulnar styloid during single-compartment radiocarpal joint MR arthrography of the wrist. Jack Porrino discusses his recent study that hypothesized this is a common finding unrelated to symptoms or examination technique.  Read the accompanying article here: https://www.ajronl...

Eric Chang discusses his study on features seen at shoulder MR arthrography that distinguish between iatrogenic contrast material extravasation and inferior glenohumeral ligament complex tears.  Read the accompanying article here: https://www.ajronline.org/doi/full/10.2214/AJR.18.20090

Nathalie J. Bureau discusses her article on the MRI findings and prevalence of supraspinatus myotendinous injuries.  Read the accompanying article here. https://www.ajronline.org/doi/full/10.2214/AJR.18.19776
